A CORPORATION OF VIRGINIA.

Specification of Letters Patent.

Patented May 13, 1913.

Application filed March 4, 1912. Serial No. 681,426.

To all whom it may concern:

Be it known that I, FRANK HINMAN PIER- PONT, a citizen of the UnitedStates, residing at Salford, Horley, in the county of Surrey, England,have invented a certain new and useful Improvement in Stamping,Punching, Shearing, or Similar Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming a part of thisspccification, and to the figures and letters of reference markedthereon.

This invention relates to stamping,punching, shearing or like machinesand has for its chief object to provide, in a machine furnished with oneor more series of tools carried or operated by a common reciprocating ormoving head, controlling mechanism or devices for each tool so that anyone or any number of these tools can be moved out of operative positionor rendered inoperative atwill, or any tool or any particularcombination of tools may be rendered operative.

In accordance with this invention, each tool has connected to or isfurnished with mechanism carried also in the movable head and undercontrol of the attendant so that any one or more of the tools whilestill partaking in the movement of the head can be withdrawn by theaction of the controlling devices so as to be inoperative on theworkpiece. Operatively connected with the movable head is a feedingdevice which, during the descent of the head, feeds a workpiece forward,preferably from a magazine, into position to be acted upon by the toolsand finally ejects the workpiece, on the ascent of the head, after thetools have acted.

The tools, according to the present invention, while secured in the headagainst yielding under the pressure of the stamping, punching orshearing operation, are mounted so that they can be withdrawn fromoperative position relatively to the head by a hand or like operatedhandle or lever connected with each tool by a cam or similarly actingdevice. During the act-ion of the tools the workpiece is forced down onto an anvil or supporting block by a springcontrolled or resilientclamping bar or member carried by the head. After the tools are raised,the workpiece is automatically raised or moved to a position to bewithdrawn by the feeding device. The ejection of the finished workpieceis controlled by a switch or latch projecting into the feed channel insuch a manner as to permit the workpiece to be fed forward by thefeeding device but on the return movement to engage the work-pieceremoveit from the control of the feeding device and direct it to a dischargeopening or chute. The workpieces or blanks are disposed in a magazinearranged vertically on the machine with the lower edge terminatingslightly above the level of a feeding slide which is connected through ayielding coupling with an arm operated by the tool-carrying head.

The invention is hereinafter described and illustrated as embodied in amachine provided with two sets or series of tools each arranged to actupon or along opposite sides of the workpiece, which is in the form of abar having projections or pieces along its two edges, some of which areto be. removed by the tools. By withdrawing one or more of the toolsfrom operation as above referred to any desired combination ofprojections may be left on the bar.

Referring to the accompanying drawingsz-Figure 1 is a front elevation ofa machine embodying the present invention. Fig. 2 is a sectionalelevation on the line 22 of Fig. 1. Fig. 3 is a view similar to Fig. 2but showing the parts at a different point in the cycle of operations.Fig. 4 is another view similarto Fig. 2 showing the parts at stillanother point in the cycle of operations. Fig. 5 is a sectionalelevation on the line 13-43 of Fig. 1. Fig. 6 is a sectional plan on theline 66 of Fig. 1. Fig. 7 is a sectional plan on the line 77 of Fig. 1.Fig. 8 is a sectional elevation on the line 8 8 of Fig. (5. Fig. 9 is afront elevation showing the mechanism for moving the various tools .intoand out of operative position. Fig. 10 is a rear elevation showing thefeeding devices.

The same letters of reference indicate the same parts throughout thedrawings.

A A are the tools; B is the movable crosshead in which the tools arecarried; C are the feeding blocks or slides; D is the bar or anvil onwhich the workpiece rests-when the tools act upon it; E is theworkpiece; and F is the magazine or holder from which the workpieces areremoved singly and fed to the tool operating position. i

' The bars E upon which the tools-A A are to operate are placed in themagazine F sired combination of projections may be left upon either sideof the bar E. be

,tools A A of the twoopposed series are similar in construction and arein the form of blocks mounted to slide to and from the plane ofoperation in guides in a block A carried by the crosshead BL] Thewithdrawal of a tool by the operator for which purpose each tool isconnected with a handle or lever A* or A.

' In the example shown each tool is provided with a pin or stud Aprojecting into a camslot A in a block A or A". These blocks are mountedto slide vertically in grooves in the block A and-to each block A isconnected one end of an operating lever. The levers A controlling thetools A have one. end slotted to receive a pin on the block A while thelevers A of thetools A are each connected toone -end of a link a securedto the block A of'a particular tool A. When a tool is to be Withdrawnfrom operative position, the lever attached thereto is drawn down (seeFig. 2); this raises the particular cam slotted block so thatthe pin Aprojecting therein, riding in the cam slot, withdraws the tool (seeFigs. 2 and 6) from operative osition.

The movements of cross hea B areuti-' lized to automatically effect thefeeding of successive bars E from a magazine to the operating devices inthe manner and by.

means about to be described. 6

Supported upon brackets (1* onadetachable frame. C are two bars 0? disosed in parallel relation and each provide inner face with a horizontalgroove or channel C the lower wall whereof is cut away,

as at C, for the accommodation of a latch C retained in position by aspring C so as to yield under pressure of a bar E when the latter isadvanced from the magazine tothe tools, but so as to obstruct the feedchannel (I and prevent the barE from being returned beneath themagazine,'wh ich latter is composed of two bars F grooved on their innersides and each mounted upon the corresponding bar C in rear of opening 0The. upper wall of the channel O in' each bar 0 s provided with anopening in register with the groove in the associated magazine bar F,the arrangement being such that a pile of bars E supported and guided bythe engagement of their opposite ends in is controlled 1 bar G. Thefingers on its mediately in rear ofbar or-anvil D for the.

accommodation'of a pivoted finger C? which is constantly pressed upwardat its outer end, the latter slightly overlapping the end of bar' D, bya. spring C and prevented from. rising too far by a stop'C.

Guided to reciprocate longitudinally upon each bar C is a head or slide0. provided with two vertical extensions or plates. C Cv separated toprovide a vertical opening between them. The plates C C extend up so jacross the channel C the plate C" being slightly higher than C? and thelatter being beveled on top at its'rear portion, as at C".

The cross head '13 is furnished at each end with an arm A each connectedby a springor resilient coupling 0 to-one arm of a le- 'ver C the latterfulcrumed at c-and con nected by its other arm'through a link'C' withthe corresponding slide C. v

When he head B descends the. bar E iS clamped between theblock D, anda'bar G sockets in the block A with one endresting upon the inner endsofthe sockets and on blocks G in the as thehead B and bar G descend,yield, under the pressure of the bar G (see Fig. and as the head theother end bearin these fingers raise the finished 'bar E to the ascendsafter the tools A- A have acted, v

level of the feed channel C to allow itto be withdrawn and ejected byand on the return movement of the slides C. As the slides C return, thefront plates'C engage the bar,

that it drops out of the machine through the opening C What I claim is:I 1. In a stamping, punching, shearing or similar machine thecombination'with a series of tools the members of which are si-'multaneously movable with and also sepa-v rately'relatively to areciprocating head, of

a cam piece coupled with each tool and a hand operated lever pivoted inthe head and connected one to each cam tially as described.

2. Ina stamping, punching shearing or.v
